Throttle Actuator Control System Low Air Flow Detected
P2175 is an OBD-II generic code for the engine control module (ECM) detecting that the air flow into the engine was not at specifications when comparing the expected amount for the throttle angle to the amount of air entering as detected by the mass air flow sensor.
The amount of air is restricted by a clogged air filter.
The air flow sensor is shorted to ground or power.
The throttle position sensor is not as specified causing the code.
The Check Engine Light will be illuminated and the code is set in the ECM memory as a fault.
The engine may lack power, surge, or have limited throttle control.
Scans for codes and documents the code in the ECM, then looks at the freeze frame data for failure
Checks the air filter and intake tube for restrictions
Checks the throttle for obstructions
Follows the manufacturer pinpoint tests for the diagnosis and replacement of the air flow sensor
Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired
Failing to clear the ECM codes after the codes are fixed
Replacing the air flow sensor without verifying the sensor has a problem
Code P2175 is a code indicating that the engine is not getting the proper air flow into the engine when comparing the throttle opening and the air flow sensor for the amount of air that should be getting into the engine. The Check Engine Light and low power condition will cause the engine to fail emissions testing.
Code P2175 is for a code that is for reduced air flow getting into the engine and can be caused by an aftermarket oil bath filter that contaminates the air flow sensor, which will lead to the sensor not detecting the amount of air entering the engine.
Regular cleaning of the air flow sensor can correct the problem temporarily. Installing a factory paper-style filter and cleaning the air flow sensor could also correct this condition.
